I've been working on various antispam measure in a phpBB3-based forum I host. Now I was thinking of an extension/mod that ties in with editing of posts (and later perhaps signatures/profiles) in that new text or edited text defaults to something like "not patrolled" and moderators could then in a special queue review text that contains links or similar item (based on heuristics).

Now the question: does such a mod exist (I didn't find one)? If it does exist and anyone has used it (or them), please include your experiences with it in the answer.
